I've been having internet problems for the past 5-6 months, and am hoping somebody can figure out what's wrong (Time Warner certainly can't).
Original cable line was installed back in 1999 for basic (VERY basic) cable with Adelphia. In 2003, I subscribed to their high speed internet, and everything was fine. I dropped it in 2005 for awhile, and didn't have any internet. Had it reactivated in 2006. Ever since then I have had connection problems.
It can't seem to stay connected to Time Warner. It'll go out, sometimes for a few seconds, sometimes for hours. Sometimes I'll unplug it, plug it back in, and it'll connect, sometimes not. Everytime I call, there's no outage in my area. They have had tech after tech out here. There's probably been 15 since February. They all say the same thing "Can't find a problem" and of course when they're here, it works fine. Usually they swap out the modem, and it works fine for a couple of weeks, and then back to the problem.
My first thought was the actual cable. I had the last guy out here run brand new cable. That didn't solve the problem. I started thinking maybe it's just the modems they give out, they're not very good. This weekend, I purchased a new modem, Linksys CM100 hoping that would fix the problem. It didn't. It still continues to go off and off, randomly. I thought about asking neighbors if they've had any problem, and everybody else here, that has high speed internet, has DSL, so that didn't help me any.
I know it probably doesn't make any difference, but I have run the modem directly into my computer, bypassing the router, and that didn't make any difference.
Nothing has changed in my setup, and I would imagine it wouldn't be a problem even if it had, because the problem is the modem can't keep it's connection.
Any ideas on how this can be fixed? Unfortunately, it's either Time Warner, or slow 1 Mb down DSL.

the new cable, was that an overhead drop from the street they replaced, or the interior cable?

that's the only thing I know you could do. If they replaced the o/h drop, replace the cable from the splitter to the modem. replace the wallplate, all of the connectors, splitters; basically, make it new. If this doesn't work, there could be a problem at the cable tap. cable internet is fragile.

He replaced both cables, as well as the ground block outside. No splitters anywhere. No wall plate.

What other devices are connected to your CATV line? Do any televisions exhibit "noise" or a lousy picture?

I'd be looking for something that is feeding garbage back into the cable. I had this problem once when someone connected an OTA antenna and CATV together to a TV. I've also had this problem like this when a filter was improperly installed at the CATV pedestal.

The techs should have a signal meter that measures both the incoming and outgoing signals from the modem.

 

[kevinturcotte]

It's only connected to the modem. Goes from the pole into a ground block, and then directly into the modem.

Everything shows up fine on the signal meter when they show up (Of course).

It could just be poor lines in your area.

I have seen some areas that have frequent connection drops like that, especially if the trunk lines are older.

Sadly not much you can do if that is the case.

I recall reading this somewhere in the forums quite some time ago. It could be too many subscribers on a single feed. Have them check to see how many subscribers are on the line feeding you. It may well be marginal.
